Question

If present ages of son and father are represented by x and y respectively and after 10 years father will be twice as old as his son . Write a linear equation of the information and draw the graph.​

Answer 1

$\underline{ \pink { At \:present :}}$

Age of Son = x years,

Father's age= y years

$\underline{ \pink { After\:10\: years:}}$

Age of Son = ( x + 10 ) years,

Father's age = ( y + 10 ) years

/* According to the problem given */

$y + 10 = 2( x + 10 )$

$\implies y + 10 = 2x + 20$

$\implies y = 2x + 20 - 10$

$\implies y = 2x + 10$

Therefore.,

$\red { Required \: Linear \: equation }\green { y = 2x + 10 }$

$Graph\: is \: attached \:above .$
